Highest temperature in NYC on July 23?

Platform comparison

Market context

The relevant real-world event is the **highest official temperature recorded at LaGuardia Airport on 23 July 2026**, with settlement based on the Wunderground daily history page for that station. The current crowd-implied 0% YES price is materially below the live market distribution, where **80–81°F** is the frontrunner at 72% and **82–83°F** is next at 19%, which suggests traders are not treating an unusually cool outcome as the base case.[1]

For context, New York City summer temperature markets tend to be driven by a few degrees of intra-day movement rather than by broad seasonal expectations, so the useful comparison is often whether a day settles in the low 80s, mid 80s, or higher. Recent reporting on late-June heat in New York, with forecasts around 100°F and heat index values near 110°F, shows how quickly synoptic heat can shift expectations when a hot air mass arrives, but the settlement here still depends on the single highest reading logged at LaGuardia rather than citywide conditions.[2] Under German GlüStV rules, access can be constrained because unlicensed gambling-style products may face stricter treatment, while US CFTC reach matters where a market could be viewed as a derivatives or event-contract product; in practical terms, a **no-KYC up to $1,500** limit means smaller positions may be opened with lighter identity checks, but larger exposure or withdrawals can still trigger verification and jurisdictional screening.

FAQ

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Tax UK has a different geo footprint.

Do I need to KYC for Polymarket Tax UK?

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Tax UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Tax UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
